Summary
Fox-IT’s penetration testing team discovered a critical vulnerability in version 5.3 of the “Keeper® Password & Data Vault” app for iPhones, iPods touch and iPads.

An update was released today that is said to resolve the issues that we identified.

We urge all users of this application to install this update as soon as they can, because user information that the app is meant to protect, including the user’s master password, was found to be stored unencrypted.
